Abstract

LOS HORNOS DE ARCO ELECTRICO (8) DE CORRIENTE CONTINUA MUESTRAN UN REGULADOR DE CORRIENTE (14) PARA LA ESTABILIZACION DEL REGIMEN DE CORRIENTE DE UN ARCO ELECTRICO (10) Y UN REGULADOR DE ELECTRODOS (18) PARA LA INFLUENCIA DE LA POSICION DE UN ELECTRODO (7) DEL HORNO DE ARCO ELECTRICO (8) Y POR LO TANTO DE LA LONGITUD DE UN ARCO ELECTRICO (10). LA REGULACION DE LA POSICION DEL ELECTRODO (7) SE CONSIGUE POR MEDIO DE UN EQUIPO (21) DE REGULACION DE ELECTRODOS HIDRAULICO, QUE EN DEPENDENCIA DE LA DIFERENCIA ENTRE UNA SEÑAL DE TAMAÑO DE CONDUCCION DEL REGULADOR DE ELECTRODO ((ALFA)SOLL) PRECALCULADO Y UNA SEÑAL DE TAMAÑO DE AJUSTE DEL RECTIFICADOR ((ALFA)ISR) SE REGULA EN LA SALIDA DEL REGULADOR (14). DE ESTA FORMA LA LONGITUD DEL ARCO ELECTRICO SE REGULA, YA QUE UN RECTIFICADOR (5) TRABAJA EN EL MEDIO CON UNA EXCITACION DE POR EJEMPLO (25 DE LA TENSION DEL SECUNDARIO DE UN TRANSFORMADOR DEL HORNO (2) Y DE UNA SEÑAL DEL VALOR TEORICO DE CORRIENTE AJUSTADA (ISOLL). POR MEDIO DE UN FILTRO PASABANDA (16) ENTRE LA SALIDA DEL REGULADOR DE CORRIENTE (14) Y UN COMPARADOR O CORRESPONDIENTE SUMADOR (17) PARA LA FORMACION DE LA SEÑAL DE DIFERENCIA ENTRE EL REGULADOR DE ELECTRODO -SEÑAL DE TAMAÑO DE CONDUCCION ((ALFA)SOLL) Y LA SEÑAL DE TAMAÑO DE AJUSTE DEL RECTIFICADOR ((ALFA)ISR) SE SELECCIONAN CON FILTROS LOS VALORES LIMITE SUPERVISADOS Y LAS FRECUENCIAS NO DESEADAS.
